2. The method of claim 1 for determining the state-of-charge of a nickel-cadmium battery wherein the batteries are initially discharged, fully charged, left standing for three hours, and then the farad capacitance thereof is measured whereby the measured capacitance indicates the state-of-charge of the battery with reference to the standard reference curve.
